Brief Background of Laptop Batteries: The primary type of battery used the harmful chemicals Nickel Cadmium (NiCd, NiCad), and was very swift to charge and was also able to handle high loads. However, these chemicals are highly toxic. Generation x of batteries, the Nickel Metal Hydride (NiMh, NiMH) batteries, now use Nickel and other rare earth metals becasue it is electrodes and Potassium Hydroxide because electrolyte. These are more green than Nickel Metal Hydride, but experience the memory effect, this will let you short lifespan. A newer type of battery will be the Lithium Ion (LiIon, Li-Ion) powered battery. Even with being smaller and lighter than NiCd and NiMH batteries, it provides the same capacity. Also, these batteries tend not to suffer from "memory effect" and have low levels of self-discharging.

The Lithium Polymer Ion Battery: This is the latest type of battery chemistry. Though this behaves just as as Lithium Ion, usually there are some important differences. The Lithium Polymer Ion Battery works on the thin plastic-like film because electrolyte, resulting in considerably reduced weight, including a greater power to weight ratio than many of the other types. They are used in Universal Laptop Batteries. Very first the type to look for, if you want a new battery to your laptop.

What are Universal Laptop Batteries?: The majority of the top manufacturers like Sony, Compaq, fujitsu, Toshiba, Panasonic, Dell, IBM, Lenovo Apple, HP, are selling the Lithium Ion battery technology. The Universal Laptop Batteries, however, use the more advanced Lithium Polymer Ion chemical. A universal battery is simply larger version from the standard laptop battery, and may power virtually any laptop.

The universal batteries are rechargeable - the AC Adapter and power lead are offered by the manufacturer. Also, producer supplies a number of tips that suit the power supply connector around the laptop. These tips give the smart electronics baked into the battery to supply electricity on the correct voltage.

Another advantage in favor of universal laptop batteries could be that the continuous usage time is perfectly up to 10 hours at a time. (Of course, there are variations according to manufacturer and style of the universal laptop battery.)

When do I need a new battery?: You don't necessarily need a new battery only following your current one is completely utilised. Some laptop manufacturers offer laptops with expansion slots that could accept a variety of peripherals, including a second battery. This second battery can double your life cycle of battery. But, if you are planning to obtain a lot of work done on that long flight, the idea may be time for you to buy a new laptop battery.

Remember: When pruchasing batteries, ensure that the supplier and also the manufacturer are reputable. Guarantee that the Supplier/Manufacturer offer full guarantee and warranty. Look at the chemistry and dimensions of the universal laptop battery before purchase. And offer the supplier considering the information about your laptop for example the make, the model, the part number, the Voltage and Current ratings (provided from the manual or underside from the laptop) in order that the supplier will help you with the most suitable battery.
